To all whom it may concern:

Be it known that I, CARL F. DIEGKMANN, citizen of the United States,residing at Bronxville, in the county of 'estchester and State of NewYork, have invented cerlected by me for purposes of illustration,

together with a slight modification thereof, and my invention is fullydisclosed in the following description and claims.

Referring to the said drawings, Figure 1 represents an exterior view inperspective of the embodiment of my invention selected by me forpurposes of illustration. Fig. 2 is a side elevation of the machine withthe inbeing shown in section. Fig. 5 is a transverse vertical sectionalview of the mechanism, parts being shown in elevation.

Fig. 8 is a diagrammatic view illustrating the mechanism forstarting the machine by the insertion of a coin in the coin operatedmechanism and for automatically stopping the machine. Fig. 9 is a detailView illustrating a modified form of cam rail. Fig. 10 is a detailsectional View of one of the liquid receiving and distributing brushes.

In the accompanying drawings I have shown my invention embodied'in ashoe polishing machine of the type illustrated in Letters Patent grantedto W. H. McConnell, No. 1,024,589 dated April 30, 1912 In the drawings,Fig. 1 represents a perspective view of the machine as it appears whenset up ready for use, the working parts being inclosed in a suitablecasing A, the upper face of which is provided'with apertures a, a abovethe foot or shoe supports, and being preferably provided with hoods a, aas shown. I also prefer to provide the top surface of the casing with asuitable seat S, for the use of the persons whose shoes are to bepolished and hand. rails C, C which may be grasped to steady theoperator in placing his feet upon and withdrawing them from the shoesupports. I also prefer to provide a starting mechanism operable by theinsertion of a coin in a slot provided for the purpose, and for convenience the coin actuated starting mechanism is preferably located in avertical y disposed casing D at one end of the main casing A between thehand railings C, C and to which the latter may be secured. Steps E ofany convenient form are also provided to facilitate persons ascendingand descend ing from the top of the main casing, and I prefer toconstruct the steps separately from the main casing, and in the mannershown in order that they maybe used at either side of the machine. Themachine proper rests upon the floor and the casing may be entirelyremoved therefrom, as shown in Fig. 2 for example, to give access to theworking parts for inspection, repair of or adjustment of the same.

The working parts of the machine are supported upon a base plate or bed,which is preferably constructed in two parts 1 and 1 which are boltedtogether, each part supporting the instrumentalities for cleaning andpolishing one shoe, the said instrumentalities being identical inconstruction and operation, so that a description of one side or half ofthe machine will, except for certain minor matters, serve for both. Forexample, the bed plate 1 is made-slightly different in shape at the rearend as shown to provide a broad supporting surface 1 to receive a motorM, and the corresponding portion 1 of the other bed plate which is muchnarrower, carries the bearings for a short transmission shaft,hereinafter referred to, which is connected by a coupling or otherwiseto one of the connected driving shafts which operate the two halves orportions of the machine.

Each of the bed plates is provided with two pillars 1, 1 and at thefront end with a curved wall 1 the upper face of which forms a cam forelevating the vertically movable shafts of the carriages as hereinafterdescribed. In this instance the cam wall is shown as cast integrallywith the bed plate but it may be made separately therefrom if desired. I

Each of the sections of the base plate is also provided with a lateraloffset portion carrying a socket in which is inserted a vertical bar orstandard, to which the discharge nozzles for the cleaning and polishingliquids are secured as hereinafter described.

vided with an upwardly extending track rail 5".

Substantially midway between the upper and lower track frames is ahorizontally disposed endless carrier 8 consisting preferably .of asprocket chain, carried by a sprocket wheel 9 on an idle vertical shaft10 mounted in bearings in the forward portions of the upper and lowertrack frames concentrically to the curved frame portions of the trackrails and by a driving sprocket wheel 11 mounted on a vertical sha t 12,mounted in bearings in the upper and lower track frames and extendingdownward to and engaging a bearing in the adjacent section of the baseplate, as shown in Fig. 5.

Below the lower track frame 5 is an endless horizontally disposeddriving chain 13, of a length corresponding substantially to the lengthof the track rails, said chain being supported at the front end of themachine by a sprocket wheel 14, on the lower end of the shaft 10, and atthe rear end of the machine by a driving sprocket wheel 15 on a verticalshaft 16, mounted in hearings in the track frames and having its lowerend engaging a bearing in the adjacent section of the bed plate, saidshaft being arranged concentrically with the curved rear portion of thetrack rails.

The track frames of each section or side portion of the machine areprovided with a plurality of brush carria es preferably six in number,which are so constructed as to be movable entirely around the endlesstrack rails before described, and are identical in structure except forcertain details which will be particularly pointed out. Each of saidcarriages is provided with a frame 20 and guiding rollers forms no partof my present invention.

VVithi'n the sleeve of the carriage is a rotatable sleeve2l, whichpreferably extends below the end of the bearing sleeve and is providedwith a sprocket wheel 62 for engaging the sprocket chain 13, as shown,the

said rotatable sleeve being held from vertical movement in the carriagein any desired way.

33 represents a vertically movable shaft extending through the rotatablesleeve, connected to rotate therewith by a key 34 and having its upperend extending through a head block 36, provided with arms 39 and beingprovided with a miter gear 38. s

The head block 36 is provided with meansv for maintaining it in apredetermined relation with the carriage frame while it is movedvertically with respect thereto, consisting in this instance of adepending guide bar 40 passing through guiding recesses or apertures inthe brackets 22, 23 of the carriage. Above the head block 36 is apivoted brush carrier comprising a sleeve 41 having a yoke 42 at itslower end, pivotally connected to arms 39 of the head block by a rod orshaft 43. A vertically disposed brush shaft 44 extends through thesleeve 41 and is provided atits lower end with a miter gear 48 meshingwith an idle miter gear 49 on the pivot bolt 43 which in turn mesheswith the miter gear 38. 7 v

Each brush carriage is provided with means for causing the brush shaftto tilt on its pivot 43, when the vertical shaft 33 is raised orlowered. To this end I have shown in this instance an actuating arm 53secured rigidly to the yoke 42 of the brush carrier and having connectedto its outer end a link 55 slotted as at 56, the slot engaging a fixedstud 57 on one of the flanges of the brush carriage. A spring 58 isconnected at one end to the carriage and at the other end to the link(or arm 53); thus holding the link with the upper end of its slotnormally in engagement with the stud 57. The specific details of thisconstruction form no part of my present invention. It'will follow fromthis construction that if the vertical shaft 33 is raised more or lessthe brush carrier .will be tilted more or lessinwardly towardhorizontal, the brush is maintained against the shoe in a yieldingmanner, and may yield in a direction away from the shoe, such yieldingbeing permitted by the'slot 56 and spring 58, so that while the positionof the brush is positively controlled as hereinafter described, it canyield to any irregularities of surface which it engages, thus enablingit to move perfectly, treat the surface it engages, and preventing anypossibility of injury to, or too great pressure upon the foot. Eachcarriage is provided with a tooth or lug 61, to engage a suitableprojection on the conveyer 8, for propelling the carriage along thetracks, and the vertical shaft 33 of each carriage is rotated during theoperation of the machine by the engagement of the sprocket wheel 62 andchain 13, before referred to.

I will now describe the means by which the vertical shafts 33 are raisedand lowered to effect the proper tilting of the brushes'as they passaround the shoe support and engage the various portions of the shoe. Forthis purpose I provide each shaft 33, at its lower end with ananti-friction bearingyand arrange around the front end of each sectionof the machine a horizontally disposed cam track or rail to be engagedby said bearings, and cause the said shafts to be raised to the requiredpositions at different portions of the travel to give the brushes therequired tilting positions. In the main figures of the drawing I haveshown the trackreferred to, and which I have indicated by 33 as beingthe top face of the wall I heretofore referred to, which may engage thelower ends of the shafts 33, but I prefer to provide the lower end ofeach shaft with a recess 33" containing a steel ball 33 (see Fig. 5) butI may employ some other anti-friction bearing if desired. Where the camtrack is stationary as shown in Figs. 2, 3, 4: and 5, it is providedwith suitable grades, as shown to impart the desired tilting movementsto the brush. In the camshown the grade m lifts each shaft 33 and causesthe brush to swing inwardly around the rear of the heel of the shoe onthe shoe support, the downwardly inclined grade at permits theshaft todescend, thus swinging the brush outwardly around the heel; the ade 1;,causes the brush to tilt inwardly where the foot narrows below the"ankle, and the grade 2 lifts the shaft gradually tilting the brush overupon the top of-the foot as the carriage passes around the toe portionuntil the high est part 2 of the cam track is reached at the front ofthe machine when the brush will lie in a nearly horizontal position,thus brushing the top of the toe portion of the shoe, the inner portionof the cam track is provided with corresponding grades to control theposition of the brush as it passes along the inner side of the foot, andin rear of theheel, in completing its circuit around the same.

In Fig. 9 I have illustrated a modification of the cam track forengaging the lower end of the shafts 33 and elevating the same. In thisinstance I employ a vertically movable cam rail, 33 which is pivoted atone end to a su port 33 at each side of the machine,

whic supports may be provided with a prethe instrumentality ;of a rotarycam 33 on the vertical shaft l2 (provided in this instance with a camgroove) and engaging one end of an operating lever 33 pivoted in theforward pedestal of the machine, and having its outer end connected withthe cam rail 33. It is obvious that by means of the cam 33 the samemovements can be imparted to the shafts 33, as are imparted by thestationary cam track.

By employing the construction just described the elevation of thevertical brush operating shafts and the brushes may be accomplishedwithout materially increasing the draft on the endless carrier, (whichresults where the shafts are forced by the carrier into contact with afixed cam surface) thus enabling the machine to be operated with lesspower. And further wear can be compensated for by renewing the operatingcam at slight expense without renewing the cam track or other parts ofthe machine; The cam 33 is detachably connected to the shaft 12, and bychanging the form of said cam, a different series of movements can beimparted to the vertical shafts and brushes if this be or becomesdesirable, as in polishing certain classes of shoes, as childrens shoesand ladies shoes, withoutaltering any of the other parts of the machine.

Any desired means may beemployed for securing the successive operationor travel of the brushes around the shoe support, In the presentinstance I have shown the same means as that disclosed in the McConnellpatent before referred to, which consists in locatinga bumper, orbumpeneframe 60, between each brush carriage and the one adjacent, eachconsisting of a metal frame similar to the frame of the carriages andhaving means for engaging the track rails, but carrying no mechanism andperforming no other function. The propelling chain 8 is of less extentthan the endless track rails leaving a dead portion at the rear of thetrack rails sufficient to accommodate all of the brush carriages andbumpers, except the carriage which is in engagement with the said chain8, and is being carried around the shoe rest, with its bumper precedingit. As

the carriage in motion reaches the end of its travel under the influenceof the chain 8, the

bumper preceding it will strike the next carriage, pushing all thecarriages and bumpers around the dead portion of the track rails andforcing the next carriage into such position that its lug 61, will engage the chain 8, and be caused to move around the shoe support in itsturn, the operation continuing until all the brush carriages have madethe circuit of the track rails, when the machine will be stopped, byshutting off the power, either by hand or automatically as hereinafterdescribed.

I prefer to provide certain of the brushes of each series with means forreceiving and distributing liquids, for cleaning or polishing the shoe,and in the present instance I haye shown the brushes arranged in thefollowing order: The first brush B receives and distributes on the shoe,a cleaning liquid; the second brush B is a polishing brush; the thirdbrush B receives and distributes a liquid polish; the next brushes B andB are polishing brushes and the last brush B9 is also a polishingbrushbut-is preferably made of cloth and may be termed the.

buffer. I do not, however, limit myselfto the particular number orarrangement of the brushes as these may be varied without departing frommy invention. The liquid distributing brushes B and B are provided withhollow cores 70, provided with lateral passages 71, extending throughthe walls of the same to the spaces between the tufts of bristles, sothat liquid inserted in the hollow core will be thrown against the innersurface of its wall and will pass through said apertures 71, and alongthe bristles to the shoe.

I provide means for supplying the desired quantity of liquid to thebrush just before it reaches the shoe to be polished, and in the presentinstance such means comprises the following instrumentalities: On theouter side of each of the base plate sections I arrange a verticalstandard 7 2 (preferably fixed in the sockets carried by the lateralextensions 1 which standards carry two pipes 73, 74 having their upperends curved inwardly toward the path of travel of the brushes andterminating in downwardly extending nozzles 75, 76 so located that theywill discharge liquid into the interior of the hollow cores of thebrushes B and B Each ofthe pipes 73, 7a is connected by a suitable pipe(not shown) as a rubber pipe or tube, with a reservoir or reservoirscontaining the liquid to be supplied, and which may be convenientlysupported Within the casing A, as indicated at 77 and 78, Fig. 1. One ofthese reservoirs is preferably filled with a cleaning fluid andconnected with the pipes 74:, 74,- and the other is connected with aliquid polish and connected with the pipes 73, 73 or I may use aseparate reservoir for each pipe if preferred, it being only necessarythat the reservoirs should be placed high enough to deliver the liquidfrom the nozzles; Each of the pipes 73 is provided with a springactuated normally closed cock 79, having a trip arm 7 9 and thepipes 74are provided with similar cocks 7 9 having each a trip arm 7 9.

The brush carriages, carrying the hollow cover brushes B B are providedeach with a selective projection 80, located conveniently on the guiderod 40 thereof, which will operate the adjacent cock 79 at the propertime in the cycle of the machine, and cause an amount of the cleaningfluid to be discharged into the hollow core of the brush and the triparms 79 and 7 9 respectively,

constitutes a selective means by which one or other of the liquids willbe supplied to each brush-having a hollow core, in accordance with thesaid relative arrangements of the parts. Each of the shoe rests orsupports 3 is provided with a base having a pair of slots 3*, 3 disposedlongitudinally of the track frame upon which it is supported and issecured in position by two screws or bolts, so that it can be adjustedback or forward and also twisted to a slight degree, to secure it in themost advantageous position with respect to the travel of the brushes.

The machine is preferably driven by means of the motor M although anysuitable source of power may be employed. When a motor is used I preferto use a self starting motor, which will start without load, immediatelyupon closing the electric circuit,'and after the armature attainssufficient speed will automatically clutch in the driving shaft by meansfor example, of a centrifugal operated clutch. Such motors are on themarket, and as the construction of the same forms no part of myinvention, it will not v be particularly described. I also prefer toinsert a breakable coupling between the moplug will be sheared andinjury to the machine prevented. Il ach section of the machine isprovided with a longitudinal driving shaft (105, 106) operativelyconnected with the vertical shafts 12 and 16 which im part motion to thepropelling chain 8 and brush operating chain 13 respectively. In thisinstance each of said shafts .105, and

106 is connected to the shaft 16 by spiralv by a train of gears 111,112, 113,114 so that the motor will drive both simultaneously.

I prefer that'the machine shall be capable of being started by theinsertion of a coin and automatically stopped when .it has caused eachof the series of brushes of each section of the machine to travel aroundthe adjacent shoe support, and to this end I prefer to provide thecasing D with a coin aperture. lVithin the casin D is a coin guide 115(see Fig. 8) at the ower end of which are located on a suitableinsulated base 116, a stationary contact 117, and a pivoted contact 118to which the wires for the motor circuit are connected, so that thecircuit will be closed by the coin which passes down the guide 115, anddrops edgewise between said contacts. This causes the motor to immediately start and as soon as the armature has gained suflicient momentumthe machine will be started and will complete its cycle of operation,thus cleaning, polishing and bufiing both shoes of the operator simultaneously. As the last carriages B, B arrive at their final positions, aprojection 119 on one of said carriages (see diagram in Fig. 8) willengage one end of a lever 120, supported on the frame work of themachine, and throw said lever, which is con-' nected by a chain or otherflexible connection 121 with a spring actuated bolt 122, in casing 0,having a hookportion for engaging a projection on the movable contact118, thus withdrawing the latter, .and permitting the coin to drop intoa coin receptacle 125. The carriage projection 119 passes entirely overthe end of trip lever 120, releasing the same, and permitting the boltto return to normal position, the movable contact 118 being returned toposition by a weight 118 (or spring). The parts 119 and 120 areindicated in Fig. 5 but the flexible connection is broken away as thecasing is removed in that figure. I also prefer to provide a lockingmechanism for locking each carriage against back lash, when it is pushedrearwardly along the inner side portion of the rails and upon the deadportion of the same, at the'conclusion of its operative travel under theinfluence of chain 8. In the present instance I have shown each of theupper track frames provided with a locking de vice, one of which isshown in detall in Fig. 7. The device consists of 'a vertically slottedcasing 126, in which is placed a piv' oted pawl 127, provided with oneor more ratchet teeth 128. A spring 129 shown in dotted lines holds thepawl in such position that its teeth may be engaged by a horizontal stud130 extending' inwardly from each of the carriages (see Fig. 5). As eachcarriage completes its travel under the influence of the chain 8, thestud 130 will pass over one of the ratchet teeth 128, thus preventingback lash or return movement and holding the carriage in position untilthe next carriage bumper engages the same. I also .prefer to providemeans for guiding the brushes during their travelv around the rear endof each section of the machine, and to apply a slight friction tocarriages pass around the rear end 'of the machine section, therefore,the engagement of said sleeves with said disk will hold the brushes fromjarring inwardly on their horizontal pivots, which might cause them tocomeinto contact and wear, and also slightly resists the onward movementof the car riages, which prevents the carriages and to move smoothlyaround the rear end of the track frame. I also provide the frame work ofthe machine with guiding means for the horizontal chains 8 and 13. Tothis end the front columns 2 (see Figs. 2 and 6) are provided withlateral brackets 2 2 on opposite sides to which are secured horizontalchain guides 2", 2 for guiding the portions of chain 8 between thesprocket wheels 9 and 11. The lower track frame 5 is also provided oneach side between the sprocket wheels 14 and 15, with depending chainguides 5", 5 which are Preferably cast integrally with the track frame5, although obviously they might be made separately and secured thereto.

In operating the machine the person desiring to have his shoes polishedwill ascend to the platform on the .top of easing A, and seat himself onthe seatv S, grasp the hand rails C, and place both feet through theapertures a upon the shoe supports 3, 3. He will then insert a coin inthe coin aperture 0 on the top of the casing.

. 100 bumpers from separating and causes them window a (see Figs. 1 and8) to the oporator and it remains in sight during the fore described andthe machine stops.

operation of the machine unt1l the operation of polishin both shoes,which proceeds s1- multaneousi y, is accomplished, when the coin dropsinto the coin receptacle, as Xe- 1- rows in Fig. 4 indicate thedirection in which the carriages travel in their circuit around the shoesupport.
